Document Summary
The synoptic winds (meaning the larger scale winds in the region) can also influence the strength of local inflows or outflows. Mesoscale cellular convection occurs in the boundary layer between the earth"s surface and the troposphere. Horizontal roll vortices, also known as cloud streets, are another product of cold-air advection and temperature inversion. When fast-flowing tidal currents are forced to pass through narrow channels, they can create dangerous tidal rapids with standing waves, large back eddies and intimidating whirl pools. Upwelling is the rise of cold, nutrient-rich water from the depths to the ocean"s surface, influenced by winds, the coriolis effect, and ekman transport. Sea fog is a type of advective fog. Radiation fog develops over land, usually at night as the ground cools beneath a stream of warm and humid air. Frontal fog forms when a warm front rises over a cold front.
